A seismic hazard model for South America, based on a smoothed (gridded) seismicity model, a subduction model, a crustal fault model, and a ground motion model, has been produced by the U.S. Geological Survey. These models are combined to account for ground shaking from earthquakes on known faults as well as earthquakes on un-modeled faults. This data set represents the results of calculations of hazard curves for a grid of points with a spacing of 0.1 degrees in latitude and longitude. This particular data set is for horizontal spectral response acceleration for 1.0-second period with a 2 percent probability of exceedance in 50 years.

Expected average annual fatalities from earthquakes are determined by using PAGER's vulnerability functions that are unique to each country. There are significant differences in fatality rates between countries, which is indicative of their relative vulnerability to earthquakes.

On April 25, 2015, a large ( M7.8) earthquake shook much of central Nepal and was followed by a series of M>6 aftershocks, including a M7.3 event on May 12, 2015. This earthquake and aftershocks, referred to as the Gorkha earthquake sequence, caused thousands of fatalities, damaged and destroyed entire villages, and displaced millions of residents. The earthquakes also triggered thousands of landslides in the exceedingly steep topography of Nepal; these landslides were responsible for hundreds of fatalities, and blocked vital roads and trails to affected villages. With the support of the United States Agency for International Development (USAID), Office of Foreign Disaster Assistance (OFDA), and in collaboration...

These data are from a 3-month long deployment of nodal seismometers that ran from May 18th, 2022 until September 1st, 2022 as part of a Distributed Acoustic Sensing (DAS) experiment above the Gorda plate (McGuire, et al., 2022). The sensors were deployed at 44 locations along Old Arcata Rd between Arcata and Eureka California (Figure 1); these locations track the approximate location of the fiber optic cable used as part of the DAS experiment. The instruments have a battery recording life of approximately one month and were swapped out in the same locations in Mid-June, and Mid-July. Thus, there are 132 instruments that were deployed at 44 distinct locations. This record covers the data from the first month (2022-05-18...
This inventory was originally created by Harp and Keefer (1990) describing the landslides triggered by the M 6.7 Coalinga, California earthquake that occurred on 2 May 1983 at 23:42:38 UTC. Care should be taken when comparing with other inventories because different authors use different mapping techniques. This inventory also could be associated with other earthquakes such as aftershocks or triggered events. Please check the author methods summary and the original data source for more information on these details and to confirm the viability of this inventory for your specific use. With the exception of the data from USGS sources, the inventory data and associated metadata were not acquired by the U.S. Geological...

This inventory describes the landslides triggered by the M6.7 central Italy earthquake that occurred on 1915-01-13 at 6:52:42 UTC. The inventory comes from the Italian Catalogue of Earthquake-Induced Ground Effects (Italian acronym CEDIT) by Martino and others (2014), which contains inventories from multiple earthquakes. To obtain the most up to date version of the entire, original catalog along with more details about its compilation, please visit the CEDIT webpage on the website of the Centre for Research (CERI) of the Department of Earth Sciences in the Sapienza University of Rome: http://www.ceri.uniroma1.it/index.php/web-gis/cedit/.

This data release pertains to the December 20, 2021, Petrolia, California, United States earthquake sequence. Data are provided in the input formats required for the Wavelet and simulated Annealing SliP (WASP) finite-fault inversion code (https://github.com/slipinversion/WASP). This includes broadband seismic data, local strong-motion accelerometer data, and the static offsets from Global Navigation Satellite Systems (GNSS) used in the finite fault inversion. Figures describing the output are also included. (Child Item: GNSS Data and Finite Fault Modeling) Also included is a high-resolution earthquake catalog surrounding the region. The catalog was produced using cross-correlations and relative relocations. (Child...

These data are from a 3-month long deployment of nodal seismometers that ran from December 22th, 2022 until March 1st, 2023 as part of a Distributed Acoustic Sensing (DAS) experiment above the Gorda plate. The deployment was done in response to the 2022/12/20 M6.4 Ferndale earthquake. The sensors were deployed at 46 locations along Old Arcata Rd between Arcata and Eureka California (Figure 1); these locations track the approximate location of the fiber optic cable used as part of the DAS experiment. The instruments have a battery recording life of approximately one month and were swapped out in the same locations in Mid-to-late January, and late February-Early march. Exceptions are that only 29 were deployed for...
The 2023 Update of the U.S. National Seismic Hazard Model defines the potential for earthquake ground shaking for various probability levels across the United States and is applied in seismic provisions of building codes, insurance rate structures, risk assessments, and other public policy. The updated model represents an assessment of the best available science in earthquake hazards and incorporates new findings on earthquake ground shaking, seismicity, and long-period amplification over deep sedimentary basins. The new model represents an update of the seismic hazard model; previous versions were developed in 1996, 2002, 2008, 2014, and 2018. This data set represents the chance of potentially damaging ground shaking...

Global Earthquake Mortality Risks and Distribution is a 2.5 by 2.5 minute grid of global earthquake mortality risks. Gridded Population of the World (GPW) Version 3 (beta) data provides a baseline estimate of population per grid cell from which to estimate potential mortality risks due to earthquake hazard. Mortality loss estimates per hazar event are are calculated using regional, hazard-specific mortality records of the Emergency Events Database (EM-DAT) that span the 20 years between 1981 and 2000. Data regarding the distribution of earthquake hazard are obtained from the Global Earthquake Hazard Distribution-peak ground acceleration dataset. In order to more accurately reflect the confidence associated with...
This data set represents the hazard curves for a grid of points with a spacing of 0.05 degrees in latitude and longitude. It represents the annual rate of exceedance versus 1.0-second spectral response acceleration.
